Re: W3DJS Raspberry Pi Ham Radio Image v2.0 Released

Well, if you're sure the hardware is not the issue, then it has to be the software setup.

If you download and install a standard Raspbian Buster image, it will already be setup to connect to a local WiFi.  I don't know what the Ham2 guy has done to setup his WiFi, so I can't comment on that.  Perhaps you should contact him directly.  There have been a fair number of people on this and other forums that are having issues with the WiFI on his setup.

You might try just using the default Buster image and then installing the ham software that you want.  It's pretty easy if you just use the built in package installer.  More complicated if you want to use "git" to get the source code and compile it yourself.

Some Raspberry Pi's come with a not working WiFi.  I have seen a few out of the couple hundred I've built.  I have a couple in my shack like like.  Try a WiFi dongle and see if that doesn't work.  You'll have to enable and setup wlan1 though.  Quality control is probably a little low, but then what do you expect for $35 or $55?

There's no way to fix it if it's bad.  Just use that one with a hardwired LAN connection, or use an separate dongle.

  I have tried 5 diff. “Make it work solutions and no joy”.  The “Killhotspot” didn’t help to make WiFi operational.

Can you please post a step by step process, from Clean (your Ham 2 image) Buster Image boot up, to operational WiFi.

I assume this was done on windows with pitnc_setparams. I'm running Linux and am unable to find a `amd64` build of pitnc_setparams. I've attempted to put the TNC back on the raspberry pi but am unable to use it anymore. I can not find the original firmware to revert the changes.

Who is the developer of pitnc_setparms? Surely there is an appropriate place to find support for their product.

And you don't have to use NOOBS ... you can install synaptic on various Raspbian (and other Debian family) images.

Select A7 Advance Options
Select A8 GL Driver
Select G1 - legacy
Select ok

Next step
Select A7 Advance Options
Select A5 Resolution
Select any resolution other than default (whatever fits your computer
monitor screen resolution
Select ok

Re: Cannot currently show the desktop

I had to change the screw resolution to get it to show. 

try that. 


Re: Cannot currently show the desktop

Diane,

edit
/boot/config.txt
and add
framebuffer_width=1900
framebuffer_height=1024

without the hdmi connected you need to set a size suitable for your screen.

Ian..
